Specification of Letters Patent. i

Application.A filed. July 10, 1909. Serial No. 506,966.

To all whom may concern: Be it known that I, .FRED'BANGERTER, a citizen of the Swiss Republic, residing in the borough of Brooklyn, county of Kings,

city and State of New York, have invented certain.. new and useful Improvements in 1Water-Meters, of which the following is a specification.

This invention aims to provide lcertain improvements in water meters especlally, though not exclusively, adapted to meters l vof `the typein which a water wheel is set in rotation by the current iowing through the meter.

An important featurey of the inventioncon sists in providing a two-partvcasing inclosing a water chamber and usingmeans for i f holding the two parts ofthe casing together )against the internal water pressure, which holding means are weaker than the parts of the-casing, so as to yield before the casing yields in case 0f freezing, and thus prevent breakage ofthe more expensive casprovisionof an inletnozzle so designed as to provide orifices of different sizes in accordance with the flow, or to provide orifices '2 2, Fig. 1. 4through the centcr and the inlet nozzle,

which introduce the water '1n diii'erent di rections respectively, or to provide for changes both in the size of the orifices and inthe direction of the flow.

The accompanying drawings illustrate an embodiment of the invention.

Figure I is a side elevation of the meter. Fig. 2 is a plan with the central chamber and 'the inlet nozzle in section", on the line Fig. 3 is a vertical section approximately on the line' 3 3 of'v Fig. 2;- Fig. 4 is a plan of the lower part of the supporting frame for the gearing. Fig. 5 isa side elevation of the gearingjFigG Ais a transverse vertical'section of the inlet pipe just beyond the nozzle, as indicated by similar to Fig. 6 with -the parts in a different position. Fig. 8 is affrontend view of the nozzle, showing the upper lip raised and the lower'lip' down. Fig. 9 is a transversesection of the nozzle on the line 9 9, Fig. 8.

Fig. `10 is a top plan view partly in sectionV of the meter with the upper part of the casing removed, showing the direction and action of the jet fromfthe nozzle with the upper lip raised.'

Referring now to the embodiments of the I vcorrodible material, these parts being provided with outward flanges C and D re- .r-ateneed Jan. 7,1913.

spectively along their meeting edges by means of which the chamber is closed.. The flange C is made slightly wider' and is recessed so that the flange D fits into it and compacts more evenly the packing ring E of paper,.rubber or the like, which lies in Y the recess in the face of the liange C.'

The Hanges are clamped together by means of three separate, comparatively small -.clamps F which may be of cheaper corrodible metal, .such ascast iron or steel, and which extend around the outer edges of the tianges and overhang the same, and are provided at their upper ends with bolts Gr for clamping thel two ianges together. The flanged joint is preferably reinforced by means of a separate ring H of cast iron or steel fitting against the flangeD and into a groove of which enter the lower ends of the bolts Gr. These cast iron or steel clamps and i'ing are more springlike than brass, and are harder', so that the bolts G can be moved down more firmly and with less friction thanwould be the` case on comparatively soft brass. The rings H will generally be made withtheir under faces minutely higher at Athe points where the clamps are located than at the intermediate points so as to make a good fit all around when pressed down by the clamping bolts. The separate ring H, however, may be omitted, the thickness necessary for stiffness being` provided in the.

flanges' C and D themselves.

The clamps F, although preferably of material which isharder than the casing, are s o yconstituted and proportioned as to be weaker than the parts of the casing so as to vield before the casing in case of freezing;`

though they are strong 'enough to hold the twov parts of the casing together and'inain tain a watertight joint against the internal water pressure. 4 In case of freezing they willburst or crack before ,any injurious strain/isbrought upon the other parts of the apparatus and. being of a vcheap material and' not necessarily finely finished, they can to a part of the casing, while the l1 lighter and ispivoted upon the heavier lipv i orifice to the volume of water passing. The

'suing from the passaofe inthe lower lip, the

be replaced for a few cents. Water meters are often required to stand a test of 150 to 200 .pounds pressure per square inch, and under such circumstances the cast iron clamps would be designed to crack or break at i310() or more pounds pressure per square inc The water wheel comprises a disk J with buckets K rotating in the lower part of the chamber and -actuated by a tangential flow from the inlet nozzle 4L (see F ig. l0), the water passingout through the outlet M. The inlet nozzle is provided with a pair of -lips N and O pivoted at .their rear ends, the

lip Nsbeingtheiheavier and being pivted 1s N. The upward movement of the lighter lip O is limited by' an extension Pat its rear end which strikes anadjacent stop P car-V ried on the heavier lip. The jet. issuing from the nozzle when the upper lip is lifted, issues from between the side-walls or cheeks' of a passa-ge t formed in the lower lip, within which passage the upper lip is.

adaptedV to project, 'so thatthe water pass.

ing therethrough is confined laterally and the particles in motion are given a common direction. The upper lip being pivotally mounted may rise and fall in the passage so as toconform the size of the opening or water therefore issues 4,from 'the nozzle in a compact stream or jet ina direction to strike thetangential bucketsof the water wheel,

which. assures that the stream of water shall have suiiicientforce and concentration to reach and strike' the water wheel and actuate the meter. m A

' `The form and direction of the stream isupper lip being lifted', is clearly :illustrated in AEig. lOof the drawing. `The nozzle with Vthe-upper lip lifted and the `stream issuing fromuthe passage in the lower lip,r is also illustrated in Figs. 8 and 9, -Fig. Bbeing a front end viewand Fig. 9 a longitudinal section of the nozzle. l These lips constitute' yielding members, the lighter one of vwhich is adapted to yield .with comparatively slightlow without the lifting of the heavier lip; while a suiiicientlystrong fiow will lift the heavierY lip and theA lighter lip -at the' same time. Vhen there is not enough flow of water tolift either ofthe lips N and O,

there is provided a minimum orifice or pair of vorifices Q. formed by grooves cut'i'n the sides of 'a tongue R onthe lower side oi the lip O... When there is a sufficient ow of water to lift the lighter lip O there is provided in addition to theorifice ororifices Q, an'additional orifice S, (F ig. 7) below the eater flow of to'provide an additional orifice T between said lip and the fixed lip U: at the front of the nozzle. By this provision of a plurality` of lips, adapted respectively to yield to flows of diiierent volumes of wateigand adapted in yieldingto provide orifices of diferent sizes, Vthe meter can be so designed as to registerthe amount of water accurately and to avoid the discrepancy which would be produced by the varying velocities of the jet directed upon the water wheel from'the nozzle if thenozzle orifice were always the same.

I use the term orifice Where toindicate the total cross-section of the space or of the plurality of spaces through. whichthe waterv issues, Aso as to' include in one case the two" openings-Q, in another case these two open.

ings andan additional opening S, and .in another case the openings Q. S vand .'I.

Inorderfto further alter the effectief the `jet upon the water wheel, one of the `orifices maybe inclined so as to introduce the water in a diiie'rent direction,.intersecting that of another orifice, so that by closingvor opening one ofsaid orifices, preferably opening or closing the other 'concurrently, the flow may be produced at one or another desired angle. For example, each orifice Q, near its outlet end is upwardlyv inclined so .that for a minimum flow, where the lighter lip Ois not lifted, the jet of water is not onlya very fine one, but is inclined so as not to strike the water wheel at the most eiiective angle.` The inner or rear portion of the orifice Q, may be forkedas shown in Fig. 3 vsoas to provide a wide entrance for the water. For example with a meter for a five-eighths inch pipe and with a nozzle of the proportions illustrated, and with the outlet, from the meterv wide open so as .to

permit a full flow, both`the lips willbe lifted to the .limitsof their movement. If

the demand at the outlet pipe is only equiva-`4 lent to a stream or an orifice' of a diameter varying from about ive-eighths to oneeighth of an inch, both lips. will also -be lifted,l but the heavier "somewhat less than Aits full opening and to an extent varying according to the demand. For a demand equal to a jet or orifice of one-eighth of an inch in diameter, the upper lipvonly will be lifted. And for a demand of one-sixteenth of an inch, both the lips will be dropped and thev supply coming from the very fine orifices Q will turn the wheel at` approximately the properrate,-a result which it has been-diicult or impossible to obtain with meters ofthis type heretofore.- i i The water wheel is mounted on theflower end of a shaft V and through a suitable intermediate` gearing rotates a gearW-which drives a fork X on the lower end -of the sha-ft of the register. The support 'for the the lower portion of the casing, and lits in a circular socket in said lower portion of the casing so as to be held firmly in place by the overhanging upper portion Ii 'of the casing. The shaft V passes through the center of the ring Y and has its upper end vsupported in a bridge, a portion c of which overlies the space within the ring; while a portion l ot' the saine bridge overlies a portion of the ring'Y and suppo-rts the upper ends of the shafts of the' gear train, the lower ends of the same shafts being supported in the ring Y. The gear train comprises a pinion c .on the shaft V which drives a gear f von a second shaft 9,' this shaft carrying a pinion zy which engages a gear on a third shaft 7c; which shaft carries a pinion Z engaging the iinal. gear W' which turns loosely on the upper end of t-he shaft V. The po-rtion d of the bridge which supports the upper ends of the shafts is elevated at its center to provide room for the pinion Z, and the bridge is fastened to the lower part of the frame by means of screws m. The tiat-topped extensions n upon wl ich .these screws are fastened are indicated in F ig. 4.

For the 'sake of durability I provide a jeweled bearing for the shaft,and which is designed preferably as illustrated in Fig. 3. The shaft is hollow to a point above the point of attachment of the water wheel, and

in the upper end Iof the hollow space is a Y sapphire o which is easily set in place and removed, being held by a hollow member 7J which engages the under side of the tapered edge of the jewel, and which is screwed into the socket in the lowerend of the shaft. The lower member of the bearing is another sapphire r/ mounted in the upper end of a pin r, to the lower end of which is attached a cap or sleeve s which screws into the base of the chamber. In case of injury to the pin 7 it may be unscrewed and another sub stituted veryreadily, and in case of stoppage the bearing is very easily accessible for inspection and renewal or repair. The lower end of the hollow holding member p is provided with a diametral notch so that it can be taken out and replaced by means of a screw-driver.

any accumulation of -dirt therein and also gives a better balance to the wheel by locating thelatter below its point of support.

l The extending of the clamps around the flanges causes the pressure to act as a transverse bending strain on the clamps so as to" The .location of the bear-` ing in the upper end of its socket preventsy the casing so as'to yield before the casingl yields in case of freezing.
